Expert on the Avaya phone system, Jack had helped me set up programing and the voice mail 6 years ago , and again two weeks ago in new office. Highly recommended. Thank you Jack

The best low voltage wiring company in Denver! Technicians were on time, professional, and knowledgeable. I highly recommend them for anyone looking for voice and data cabling work.



We worked with Jack and his crew at Rocky Mountain Tel-Tech to run data cabling at our new facility. Everyone was great to work with and they went out of their way to get the job done quickly and cleanly. I would highly recommend talking with them if you have any voice or data cabling projects coming up!

What an awesome company! I had an issue that was plaguing my Avaya phone system for quite some time and even Avaya's customer support could not help solve the problem. Jack was able to walk me through the steps over the phone allowing me to re-program my office phone system and resolve the issue in just a few minutes. Jack is extremely knowledgeable, easy to get in contact with and a true professional. I would recommend Jack and Rocky Mountain Tel-Tech to anybody. Thank you from a very satisfied customer!

We have been using Rocky Mountain Tel-Tech for our Avaya Partner Mail System that is ANCIENT! If you have any experience with Avaya then you know how convoluted the codes can be to crack to get into the system's back end and maneuver your way around. Jack has made himself available in many pinches to come over to YAO Clinic and help us out sometimes on the same day. He has been here to coordinate upgrades with Comcast and helps us out by phone with things we can't possibly seem to figure out on our own. He will usually fix things in less than 5 minutes after our hours of struggling. Additionally, he is friendly and up beat and a great guy to be around. We highly stand behind the work of Rocky Mountain Tel-Tech!
